[tor-relays] Expiration time from torbulkexitlist

[Julien Moutinho]

Hello Tor fans,

New to Tor here, nonetheless this month I've tried to work
on some type-checking and hardening of Tor in NixOS
(see https://github.com/NixOS/nixpkgs/pull/97740 in case this interests you),
hence I've tested Tor as an Exit node a few hours behind 80.67.180.251,
as visible in: https://collector.torproject.org/recent/exit-lists/2020-09-22-01-02-00
> ExitNode 483F3347218DA225540D67AC3B9D48235A23DB89
> Published 2020-09-07 19:22:15
> LastStatus 2020-09-08 01:00:00
> ExitAddress 80.67.180.251 2020-09-08 01:59:25
And, if I'm not mistaken, only used it as a non Exit node since then
(mostly to test a new NixOS abstraction around onion services).

It's now 14 days past my Exit node test, yet that IPv4
is still listed in: https://check.torproject.org/torbulkexitlist
despite https://lists.torproject.org/pipermail/tor-project/2020-March/002759.html
announcing that:
> This list is updated at most once every 40 minutes depending on the
> number of exit relays in the network at the time, fetching it every hour
> would be reasonable.

A quick grep in https://collector.torproject.org/archive/exit-lists/exit-list-2020-07.tar.xz
shows that in the past at least some exit nodes have been removed after one month:
> $ grep LastStatus exit-list-2020-07/13/2020-07-13-18-02-00 | sort -r | tail -1 
> LastStatus 2020-06-15 03:00:00
> $ grep LastStatus exit-list-2020-07/13/2020-07-13-19-02-00 | sort -r | tail -1
> LastStatus 2020-07-11 20:00:00

Am I right to assume that one month is the expiration time from torbulkexitlist?
And can I do anything to trigger the removal before that delay?

Thanks in advance for your answers,
Julien
